  • 摘要: 伴随我国核能的开发与高效利用,铀已成为我国地表水、地下水和土壤的常见污染物之一,从含铀废水中去除U(VI)已成为亟需解决的环境问题。本工作以膨润土(BTN)、磷酸氢二钠、硝酸钙为原料,采用简单易行的一步水热法成功制备出羟基磷灰石(HAP)改性膨润土复合材料(HAP/BTN)。考察了HAP/BTN对水溶液中铀的吸附性能,利用单因素试验和正交试验探讨了pH、转速、温度、投加量、时间对吸附性能的影响。试验结果表明,在pH=6.0、转速=100 r·min−1、室温(298.15 K)、HAP/BTN投加量1 g·L−1、吸附时间t=30 min时,该吸附材料对10 mg·L−1含铀废水的去除率可达98%,最大吸附量为186.45 mg·g−1。吸附过程更符合Langmuir模型和准二级动力学,热力学参数表明HAP/BTN对铀的吸附是自发吸热的过程,结合XPS及XRD的结果证实了HAP/BTN吸附铀主要归因于络合反应、化学吸附、静电吸附和离子交换作用。
